Application led June 28, 1906., lSerial No. 323,912.

To all 'whom it may copcem:

Be it-known that I, VIOLA MoELnEE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements inEnvelops; and l do hereby declare the following to be a full, clear, and exact description of the in -vention, such as will enable others skilled in the art to.whicli it appertain's tomake and use the same. p

y The primary object Aof this invention is to provide anenvelop with' a erfectly smooth interior, free 'from all'l edges iable to interfere' with the insertion or removal of the contents. And a further object is to provide an envelop ,wliich'will be securely 'closed at all its corners,

and so formed that the front will be readily ishable from the back, thereby avoiding a confusion in addressing and sealing; and further to provide an envelo wherein the contents can be inserted, the ap sealed,

. Fig. 4 shows the other end section folded into ingthereby a smooth interior, the left hand l ltion 4 alongjone'e the upper edge of the envelop, and its other position.- Fig. 5 is a face view of the envelo enve op sealed and ready for mailing.

In carrying out my invention I form the rear section 1 of exactly the same size as the. front section 2, the latter, however, having a slight cut-in at 3 along its upper free ed e. The rear section 1 is a continuation of t e yfront section 2, being folded back over the latter along the bottom line. vAfter the rear section is so folded, as shown in Fig. '2, formend section 4` (viewing the envelop from the rear) is folded over the outer face' of'rvear section 1, being secured thereto by paste applied to its two edges, as at 5. This end secge forms a continuation of edge is c ut diagonally, but on a line short of thediagonally opposite corners of the envelop., After the end section 4 is secured,

the other end section 6 is folded over the rear section 1 and the previously folded end sec- I. tion 4. y It also is provided with mucilage per edges are in length equal to the length of 7o Fig. 6 is a similar 'view with the' `tltious access to t e envelo along its edge, as at 7, so that it will securely adhere to both therear section 1 and the end section 4. These two end sectionssecurely close the ends of the envelop, and being outeo side of the rear section, a perfectly smooth pocket' is formed without any edges within the envelop, thus permitting the contents to be readily inserted and removed. The in tersecting edges of the two end sections, on e5 the outside of the rear section,` give to the completed article the necessary appearance to differentiate at a glance the front from the The two end sections along their up` the envelop, but the inner section 4 may be shorter.A f

The end section 6 is formed along its upper edge with a sealing fiap 8 whic extends throughout the full length of the envelop,

and will fold down over the front section 2 thereof sufficiently far topermit the Inucilage9 along its edge to adhere to the front section without engaging that portion of the contents which may be exposed through the so cut-in 3. The sealin flap is further secured in place by theapp ication of the ostage stamp over the edge thereof, at the ee end of the outer fla as'indicated in Fig. 6 The lower edge of t e end section 6 is cut away on `85 a diagonal line that extends froml its lower edge near its junction to the front section 2 upwardly to its outer edge.

From what has been said it will be seen' that the front and rear sectionsbeing of correspending formation, and folded one u on the other, and held by the end sections w lch are folded over the rear section, a perfectly smooth pobket is rovided, so that surre without disengaging the flap om the face of the envelop or destroying the latter in a manner that would be readily detected. My envelop also possesses the further advantage 'that the address side is perfectly smooth until 100- the flap is sealed thereon making it readily distinguishable from the rear side, and it may be addressed, the contents inserted, and the envelop sealed and stamped without the necessity of turning it over.

l 'claim as my invention 1. An envelop com risinga front section, 'and a rearseption, fol ed one upon the other and of substantially the same formation, op#

posite end sections desi ned to be folded one 110l upon the other and bot upon the outside of the rear section, and a sealing Hap carriedby is impossib e f one of said end sections for folding over the edge of thev front section.

2. An envelop com rising a front sec-tion and a rear section, fol ed one uponthe other and of substantially the same formation, end sections extending` from the front section and designed to be folded one upon the other and both on the outside of the rear section to which they are secured, the outer of the two end sections having along `rts up er edge a sealing 'flap designed to be folded) over the edge of the front section.

8, The herein described envelop comprising a front section and a rear section of substantielly corresponding formation, the rear section being folded upon the front section, two end sections extending from the ends of l the front section, seid end sections having each a diagonal extended edge and designed to he secured, one to the outer face of' the rear section and the other to the outer fece of said reer section and to the rst noted end section, and a sealing flap extended from the upper edge'of the secondnoted end section designed to fold over the edge of the front section.

ln testirnonyvhereof, l have signed this specification in the presence of two subscribing witnesses.
